My loose use of terminology - thus, my bad. Reflection. Red was the color. I think we had LED flashlights - I did - not sure about the others. That night, I don't recall any moon.
Yes, we heard a whisper of movement, and we were expecting a cat or maybe even a bear to come that night for the deer - so we were sort of listening for signs of it being either dragged or eaten. Neither one of those noises - no real wind that night - so everything was silent. Just heard a couple small, barely discernible snaps - probably small twigs being stepped on.
It was a very steep pitch to directly below, a semi-level area where they were traversing across the slope - and yes, there was water about forty or fifty yards further along the direction they were traversing to get to the deer.
This was an older location. Yes, it was directly below where we camped. Since we went to bed rather early - it must have been somewhere within an hour and a half of sundown. I believe there were caves in the area, and in fact - while I didn't check it out - I felt strongly that there was a cave or large overhang below us and maybe 60-75 yards to the east - and I just had a gut feeling that some lived down there, as one was spotted in that location when it came out and stood still on a huge rock outcrop looking south -
Slightly higher than us (we were about 150 feet below the absolute peak) was a large cluster of huge boulders. Before this ever happened, I told a guy 'every time I look at that cluster of boulders, I get a bad feeling.' He said that was funny as he did the same thing - and no one ever approached it.
I'd say that I never thought of whether or not seven individuals would be a large group or not. Just a lot more than I wanted to know about. I didn't even want to know about one! This area was so rich in deer herds - if one went to sleep on a few game trails - you'd probably get trampled to death by deer. Just going up on an ATV, a few times I found myself right in the middle of a herd, and could have slapped three or four right on their rumps! The dumb things would run with me right up the cut!
This area provided lots of game, water, isolation, and minimal intrusion. Yes, the locals are aware not just of this "clan," but there are apparently clans every few miles. One guy sees them on the road or crossing the road on his way to work - several miles away from this site - on a regular basis.
As to your question about the 'people who should know about them' - not sure who those people are? I mean, everyone thereabouts know these things are everywhere - and everyone pretty much minds their own business. No law around, no city, and it's difficult country. I saw one guy who had a "Bigfoot Crossing" by the road in front of his house - and at first I thought it was a joke. After the fact - maybe not.
I mean, you could hide a few infantry divisions within thirty square miles - so these things have no trouble detecting folks approaching along the only road - and avoiding the same. So it's not like a group of seven, or even seventy would have a problem remaining undetected.
On occasion, as one is going back down - they'll throw a good sized rock out in the road in front of you, or just push a tree over to block the road - and you'd have to get down and move the tree to continue back down. Just letting you know they're not real welcoming.
